Abstract

Methods and devices are provided for improved environmental protection for photovoltaic devices and assemblies. In one embodiment, a photovoltaic device module is provided comprising of a multi-ply module encapsulant, a bottom module layer, and a plurality of solar cells. The multi-ply module encapsulant includes one or more discrete layers comprising of at least a first module layer and at least a second module layer. The plurality of solar cells may be sandwiched between the multi-ply module encapsulant and the bottom module layer. At least one of the cells has a protective layer that provides a level of moisture resistance equal to or higher than any of the layers above the cells. The protective layer is typically above the solar cell and light passes through the multi-ply module encapsulant and the protective layer to reach the solar cell.
